It depends on the direction of the internal vanes.........they are meant to throw the cooling air out via centrifugal force.

As all have said it's the internal vents that are important. The grooves or slots you can see on the disc face smetimes go one way sometimes the other depends on manutacturer. There's another similar diagram to the above here which to me is clearer.

As Ian says (and my post number 3), the internal vanes are venting air outwards the way you have fitted them
